In a 137-second video, which Deora shared on Twitter, the industrialist says: "Milind is the man for South Mumbai."Banker Uday Kotak is also amongst those who have endorsed the 42-year-old Congress leader in the video clip.

" Having represented South Mumbai for 10 years, I believe, Milind has in-depth knowledge of social, economic and cultural ecosystem of the South Bombay constituency," Ambani says in the video montage shared by Deora on the micro-blogging site.

Deora is pitted against Arvind Sawant of the Shiv Sena, who is also the sitting MP from South Mumbai Lok Sabha constituency, a stronghold of the Sena.

The young leader, who lost the constituency in 2014 general election and was recently appointed Mumbai Congress president, captioned the video saying, "From small shopkeepers to large industrialists - for everyone, South Mumbai means business. We need to bring businesses back to Mumbai and make job creation for our youth a top priority."Mukesh Ambani's endorsement of a Congress candidate has come at a time when Rahul Gandhi has been attacking Anil Ambani in his electioneering.

"Prime Minister Narendra Modi took out Rs. 30,000 crore from Indian Air Force and put it in the pocket of Anil Ambani," Rahul has repeatedly said. The Gandhi scion also has time and again said, "chowkidar chor hai" referring to Prime Minister Narendra Modi.
